HATCH-FASTENER FOR VESSELS.

SPECIFICATION formingpart of Letters Patent No. 642,291, dated January 30, 1 900. Application filed May 9, 1899. Serial No. 716,110. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. BOWMAN, a citizen of the United States of America, and a resident of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Hatch-Fasteners for Vessels, of which the following is a specification.

This invention relates to hatchways for ves sels and it consist-sin providingafastener for holding down the hatch-cover, having for its object to supply a simple, easy, and ready means of securing the cover and the canvas over the cover against leakage or storms.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a View of a part of the coamiug of a hatchway, the cover, and canvas covering, showing my new fastener attached, in perspective. Fig. 2 is a vertical section of the same. Fig. 3 is a perspective view of the fastener shown open.

A represents the coamin g of a vessels hatchway, B the hatclrcover, and O the canvas covering the same.

D is a bracket attached to the coaming about midway between the deck and the top of the coaming.

E is a hook hinged to the bracket by a peculiar slip-joint, whereby the hook maybe raised or lowered when adjusting it onto the cover.

F is a split or divided arm on the bracket, standing at an angle and leaning toward the coaming. The hook E is formed with an incline E, forming a dovetail joint when in place in the bracket, the purpose of which is that when the batten and wedge are inserted the hook will be firmly fastened in the bracket.

G is a projecting leaf on the hook, having a slot g parallel with the incline E, as seen in dotted lines in Fig. 2. The leaf is inserted in the slot or space e in the arm F, and a pin f is put through the eyes in the upper end of the arm and through the slot 9 in the leaf, thus providing a pintle on which the hook may turn.

H is a batten put in between the coaming and the hook, designed for firmly dovetailing the hook in the bracket, also for holding the canvas.

J is a Wedge for binding the batten and hook in place.

K is a bar placed across the top of the canvas, having its ends inserted under the hooks at two opposite sides of the hatch-cover for the purpose of holding the canvas down and prevent wind getting under.

As many of these fasteners may be used on a hatchway as desired, and from their character it will be seen that they are a simple' and effectual means for the purpose intended.

Having described my invention, what I claimis 1. The combination with the coaming of a hatchway of brackets D having slotted arms F, hooks E having dovetails E and leaves G, having slots g, slidingly attached to the arms F, substantially as shown and described.

2. The combination with the coaming of a hatchway and the cover and canvas therefor, of the brackets D, having slotted arms F, hooks E having dovetails E and leaves G having slots g, the battens H, and the wedges J, constructed and adapted to operate substantially as and for the purpose set forth.

Signed by me at Cleveland, Ohio, this 6th day of May, 1899.
